A disazo compound is provided which is represented by the formula (I): <IMAGE> (I) <IMAGE> (wherein, R1 and R2 each stands for hydrogen, a lower alkyl group with 1-4 carbon atoms, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aromatic group, or a substituted or unsubstituted hetero ring group. R1 and R2 may be the same or different. And, R1 and R2 may mutually bond to form a ring). This disazo compound may be obtained by diazotating 2.6-diaminoanthraquinone and reacting the same with a coupler represented by the formula (IV): <IMAGE> (IV) (wherein, R1 and R2 are the same as defined above). Further, a multilayer type electrophotographic element is provided which comprises a charge carrier generating layer and a charge transfer layer and uses, as a charge carrier generating substance, a disazo compound represented by the formula (I).
